Erratic NSW driver 'six times over limit'

A motorist spotted driving erratically northwest of Sydney was allegedly nearly six times over the legal alcohol limit.

The 56-year-old was seen driving erratically on George Street, Windsor, overnight before officers stopped him for a breath test, which was positive.

The Londonderry man was arrested and at the police station allegedly returned a breath analysis reading of 0.299, police said on Tuesday.

His driver's licence was suspended and he is due to face the Windsor Local Court on November 13 charged with high-range prescribed concentration of alcohol - second offence.
